COR10RA'J."IONy OF DELAWARE PRINTING DEVICE FRAME BLANK Application lekd December This invention relates to frames for printing devices of that class which are adapted to be stored in accordance with a card index system "and to be run throughl addressing or commonly comprise ai frame` and one or more plates having printing characters embossed thereon the frame being provided with retaining means for detachably securing the 10 plate orplates in place thereon. To accommodate the requirements of trade the printing devices have been made up in many types requiring the provision of special dies for stamping the frames and the number of '15 types is constantly increasing with the extension of uses of the printing devices. Each type of printingdevice has heretofore been made as a separate unit and this has required the provision of a great many dies some of The 'sales of the different types are more orv less irregular in volume and the result is that large quantities of the different types of frames are constantly vcarried in stock. .l Where dies are 25 used interchangeably for different typesdelays occur sometimes in filling a large order for a certain type because of the use of the dies inmaking some other type or 'types. l/Vherecertain dies areused in producing a 130 number of different types there `is always the tendency to confusion and delay and the only other recourse is Vth'eprovision of a complete set of dies for' each type-which would include many duplicates. v

The generic objectr of the invention isto provide a standard frame blank which is partly made in the form of av frame and which can be comi'vleted in any type desired. It is also the object to enable the standard frame blank to be made in quantities on'a production basis, and kept on hand' to' be quickly linished inany typerequired to fill orders received orto maintainY stock requirements according to any systenithat may beV prescribed.l

I have illustrated the invention in the accompanying drawing in a formsuitable for the purpose and referring thereto,

The spacing flanges 9 space the printing devices apart in a drawer or in a stack and thereby protect the faces of the printing Vcharacters that are subsequently mounted on the frame.

The ribs of the 4spacing flanges of one printing device will engage the facing sections of another print- `ing device to space the devices apart, as above set forth. The facing sections form rsmooth surfaces for handling theprinting devices and for the ribs of another. printing` Additional In orstock of each type to lill small orders.

der to provide a standard frame blank linished as completely as possible for the many varieties of frames it is necessary to have the retaining devices on the blank made and disposed in a manner to function properly in any type of frame. lt has been customary to use beats at the top and bottoni of the frame as shown in the drawing but the retaining devices at the ends of the frame have been made of different kinds and in diderent sizes and shapes designed for each particular frame, and this has involved, as before stated, the provision of as many different dies as there are different lretaining devices. l avoid this by providing three end stops of substantially equal length spaced apart and from the top and bottom of the' blank and arranged in vertical alignment adjacent each end of the frame. l

have found that if these end stops aggregate in length substantially one-half the height of the frame from top to bottom they vwill serve for any of the types of printing devices which have been used and for any others.

My invention enables the standard blank Figs. l, 2 to be made as a stock production job in a continuous run with one set-up of dies on a machine which may continue from 39 day to day according to trade requirements.

rllhis also enables the work to be done by operators proficient in the production of the particular product and promotes efficiency and uniformity of product. lt enables the factory to keep on hand a supply of standard blanks, which are partly made frames, and which can be turned over to other operators to finish quickly into different types of frames to supply particular orders. This also promotes efciency and uniformity of product and enables orders to be filled with Vgreater speedrthan has been customary where is only necessary to maintain a stock of the standard blanks 'ou hand `and to keep supplying these standard blanks as fast as they are required for use in making up different types of frames to supply orders and since the finishing operation can be performed quickly it is believed. that it will not be necessary to keep on hand any more than a small The invention simplifies the die operations and systematizes the work so that production may be increased and costs reduced.

y I have shown the invention in a form whichl find satisfactory to accomplish the objects of the invention but changes in the details of construction may be made to satisfy different requirements and l reserve the right to make any changes within the scope of the following claims.

I claim: y

A standard blank for printing device frames having at each end a plurality of retaining devices of substantially equal length spaced apart in equal amounts from each other and from the top and bottom of the blank and arranged in alignment, the retaining devices at one end being disposed opposite the retaining devices at the other end of the blank.

Q. A standard blank for printing device. frames having at each end a plurality of retaining devices spaced apart in alignment, the aggregate length of said devices at each end of the blank being substantially equal to one-half the height of the blank from top to bottom thereof, the retaining devices at one end being disposed opposite the retaining de.- vices at the other end of the blank. y

3. A lstandard blank for printing device frames having at each end a plurality of retaining devices kspaced apart from each other Aand from the top and bottom of the blank, the retaining devices at each end of the blank arranged iu alignment, the aggregate length of said devices at each end of the blank being substantially equal to one-half the height of the yblank from top to bottom thereof, the retaining devices at one end being disposed opposite t-lie retaining devices at the other end of the blank. ,.95
